FIELD

Provided herein are compounds that are broad-spectrum protein kinase binding agents, detectable tracers comprising such compounds, and method of use thereof for the detection of protein kinases.

BACKGROUND

The human genome contains about 560 protein kinase genes, and they constitute about 2% of all human genes (Manning et al. (2002) Science 298 (5600): 1912-1934.; herein incorporated by reference in its entirety). Up to 30% of all human proteins may be modified by kinase activity, and kinases are known to regulate the majority of cellular pathways, especially those involved in signal transduction. The chemical activity of a kinase involves transferring a phosphate group from a nucleoside triphosphate (usually ATP) and covalently attaching it to specific amino acids with a free hydroxyl group. Most kinases act on both serine and threonine (serine/threonine kinases), others act on tyrosine (tyrosine kinases), and a number act on all three (dual-specificity kinases) (Dhanasekaran & Premkumar (September 1998). Oncogene. 17 (11 Reviews): 1447-55.; herein incorporated by reference in its entirety). Aberrant kinase signaling is associated with many diseases and conditions.

U.S. Pat. Pub No. 2014/0323346 and Zhang et al. (J. Proteome Res. 2013, 12, 3104-3116), both of which are herein incorporated by reference in their entireties, describe protein kinase binding agents. Improved kinase ligands with broad specificity are needed to allow cellular kinase profiling, kinase purification, etc.

DETAILED DESCRIPTION

Provided herein are compounds that are broad-spectrum protein kinase binding agents, detectable tracers comprising such compounds, and method of use thereof for the detection of protein kinases.

In some embodiments, provided herein are compounds that bind a broad spectrum of protein kinases (e.g., specific to protein kinases, but not specific among protein kinases). In some embodiments, compounds CC-1852, CC-1861, and/or CTx-0294885:

are provided. In some embodiments, provided herein are compounds or molecular entities comprising a CC-1861, CC-1852, and/or CTx-0294885moiety:

a functional element (e.g., attached to the nitrogen at the 4-position of the piperazine of CC-1861, CC-1852, CTx-0294885). In some embodiments, provided herein are analogs or derivatives of CC-1852, CC-1861, CTx-0294885, and/or compounds or molecular entities comprising analogs or derivatives of CC-1852, CC-1861, CTx-0294885, and a functional element (e.g., analogs or derivatives of CC-1816, CC-1817, CC-1803, CC-1804, CC-1290, CC-1294, etc.). In some embodiments, CC-1852, CC-1861, CTx-0294885, or an analog or derivative thereof is attached directly (via a single covalent bond) to a functional element. In some embodiments, CC-1852, CC-1861, CTx-0294885, or an analog or derivative thereof (e.g., CC-1816, CC-1817, CC-1803, CC-1804, CC-1290, CC1294, etc.) is attached indirectly (via a linker) to a functional element.

In some embodiments, compounds herein (e.g., comprising CC-1852, CC-1861, CTx-0294885, analogs or derivatives thereof, etc.) incorporate reactive groups suitable for chemical conjugation to a functional element (e.g., detectable element, linker, etc.). These reactive groups may be present on the compound (e.g., at the 4-position of the piperazine of CC-1852, CC-1861, CTx-0294885, analogs or derivatives thereof, etc.) or connected by a suitable linker (e.g., connected to the 4-position of the piperazine of CC-1852, CC-1861, CTx-029488, analogs or derivatives thereof (e.g., CC-1816, CC-1817, CC-1803, CC-1804, CC-1290, CC-1294, etc.), etc.). In some embodiments, the reactive group on the compound is configured to react specifically (e.g., via bioorthogonal, or click chemistry) with a reactive partner that is present or has been introduced on the functional element. An exemplary click reaction is copper catalyzed click where the compound bears an alkyne or an azide, and the functional element bears the complementary group (e.g., an azide or an alkyne). Mixing these two species together in the presence of an appropriate copper catalyst causes the compound to be covalently conjugated to the functional element through a triazole. Many other bioorthogonal reactions have been reported (for example Patterson, D. M., et al. (2014). “Finding the Right (Bioorthogonal) Chemistry.” ACS Chemical Biology 9(3): 592-605.; herein incorporated by reference in its entirety), and compounds (e.g., comprising CC-1852, CC-1861, CTx-0294885, analogs or derivatives thereof (e.g., CC-1816, CC-1817, CC-1803, CC-1804, CC-1290, CC1294, etc.), etc.) and functional elements incorporating complementary reactive species are embodiments of the present invention.

In some embodiments, linkers connecting the compounds herein (e.g., comprising CC-1852, CC-1861, CTx-0294885, analogs or derivatives thereof (e.g., CC-1816, CC-1817, CC-1803, CC-1804, CC-1290, CC1294, etc.), etc.) to a functional element (e.g., detectable element, solid surface, etc.) are provided as part of the compositions herein.

Methods to detect a particular functional element, or to isolate a composition comprising a particular functional element and anything bound thereto, are understood.

In some embodiments, a functional group is or comprises a solid support. Suitable solid supports include a sedimental particle such as a magnetic particle, a sepharose, or cellulose bead; a membrane; glass, e.g., glass slides; cellulose, alginate, plastic, or other synthetically prepared polymer (e.g., an Eppendorf tube or a well of a multi-well plate); self-assembled monolayers; a surface plasmon resonance chip; or a solid support with an electron conducting surface; etc.

Exemplary detectable functional elements include haptens (e.g., molecules useful to enhance immunogenicity such as keyhole limpet hemacyanin), cleavable labels (e.g., photocleavable biotin) and fluorescent labels (e.g., N-hydroxysuccinimide (NETS) modified coumarin and succinimide or sulfonosuccinimide modified BODIPY (which can be detected by UV and/or visible excited fluorescence detection), rhodamine (R110, rhodols, CRG6, Texas Methyl Red (TAMRA), Rox5, FAM, or fluorescein), coumarin derivatives (e.g., 7 aminocoumarin, and 7-hydroxycoumarin, 2-amino-4-methoxynapthalene, 1-hydroxypyrene, resorufin, phenalenones or benzphenalenones (U.S. Pat. No. 4,812,409)), acridinones (U.S. Pat. No. 4,810,636), anthracenes, and derivatives of alpha and beta-naphthol, fluorinated xanthene derivatives including fluorinated fluoresceins and rhodols (e.g., U.S. Pat. No. 6,162,931), and bioluminescent molecules (e.g., luciferase (e.g., Oplophorus-derive luciferase (See e.g., U.S. application Ser. No. 12/773,002; U.S. application Ser. No. 13/287,986; herein incorporated by reference in their entireties) or GFP or GFP derivatives). A fluorescent (or bioluminescent) functional element may be used to sense changes in a system, like phosphorylation, in real-time. A fluorescent molecule, such as a chemosensor of metal ions, may be employed to label proteins which bind the composition. A bioluminescent or fluorescent functional group such as BODIPY, rhodamine green, GFP, or infrared dyes, finds use as a functional element and may, for instance, be employed in interaction studies (e.g., using BRET, FRET, LRET or electrophoresis).

Another class of functional elements includes molecules detectable using electromagnetic radiation and includes, but is not limited to, xanthene fluorophores, dansyl fluorophores, coumarins and coumarin derivatives, fluorescent acridinium moieties, benzopyrene-based fluorophores as well as 7-nitrobenz-2-oxa-1,3-diazole, and 3-N-(7-nitrobenz-2-oxa-1,3-diazol-4-yl)-2,3-diamino-propionic acid. Preferably, the fluorescent molecule has a high quantum yield of fluorescence at a wavelength different from native amino acids and more preferably has high quantum yield of fluorescence that can be excited in the visible, or in both the UV and visible, portion of the spectrum. Upon excitation at a preselected wavelength, the molecule is detectable at low concentrations either visually or using conventional fluorescence detection methods. Electrochemiluminescent molecules such as ruthenium chelates and its derivatives or nitroxide amino acids and their derivatives are detectable at femtomolar ranges and below.

In some embodiments, a functional element is a fluorophore. Suitable fluorophores for linking to the compounds herein (e.g., to form a fluorescent tracer) include, but are not limited to: xanthene derivatives (e.g., fluorescein, rhodamine, Oregon green, eosin, Texas red, etc.), cyanine derivatives (e.g., cyanine, indocarbocyanine, oxacarbocyanine, thiacarbocyanine, merocyanine, etc.), naphthalene derivatives (e.g., dansyl and prodan derivatives), oxadiazole derivatives (e.g., pyridyloxazole, nitrobenzoxadiazole, benzoxadiazole, etc.), pyrene derivatives (e.g., cascade blue), oxazine derivatives (e.g., Nile red, Nile blue, cresyl violet, oxazine 170, etc.), acridine derivatives (e.g., proflavin, acridine orange, acridine yellow, etc.), arylmethine derivatives (e.g., auramine, crystal violet, malachite green, etc.), tetrapyrrole derivatives (e.g., porphin, phtalocyanine, bilirubin, etc.), CF dye (Biotium), BODIPY (Invitrogen), ALEXA FLuoR (Invitrogen), DYLIGHT FLUOR (Thermo Scientific, Pierce), ATTO and TRACY (Sigma Aldrich), FluoProbes (Interchim), DY and MEGASTOKES (Dyomics), SULFO CY dyes (CYANDYE, LLC), SETAU AND SQUARE DYES (SETA BioMedicals), QUASAR and CAL FLUOR dyes (Biosearch Technologies), SURELIGHT DYES (APC, RPE, PerCP, Phycobilisomes)(Columbia Biosciences), APC, APCXL, RPE, BPE (Phyco-Biotech), autofluorescent proteins (e.g., YFP, RFP, mCherry, mKate), quantum dot nanocrystals, etc. In some embodiments, a fluorophore is a rhodamine analog (e.g., carboxy rhodamine analog) such as those described in U.S. patent application Ser. No. 13/682,589, herein incorporated by reference in its entirety.

In addition to fluorescent molecules, a variety of molecules with physical properties based on the interaction and response of the molecule to electromagnetic fields and radiation find use in the compositions and methods described herein. These properties include absorption in the UV, visible, and infrared regions of the electromagnetic spectrum, presence of chromophores that are Raman active and can be further enhanced by resonance Raman spectroscopy, electron spin resonance activity, and nuclear magnetic resonances and molecular mass, e.g., via a mass spectrometer.

In some embodiments, a functional element is a capture element. In some embodiments, a capture element is a substrate for a protein (e.g., enzyme), and the capture agent is that protein. In some embodiments, a capture element is a “covalent substrate” or one that forms a covalent bond with a protein or enzyme that it reacts with. The substrate may comprise a reactive group (e.g., a modified substrate) that forms a covalent bond with the enzyme upon interaction with the enzyme, or the enzyme may be a mutant version that is unable to reconcile a covalently bound intermediate with the substrate. In some embodiments, the substrate is recognized by a mutant protein (e.g., mutant dehalogenase), which forms a covalent bond thereto. In such embodiments, while the interaction of the substrate and a wild-type version of the protein (e.g., dehalogenase) results in a product and the regeneration of the wild-type protein, interaction of the substrate (e.g., haloalkane) with the mutant version of the protein (e.g., dehalogenase) results in stable bond formation (e.g., covalent bond formation) between the protein and substrate. The substrate may be any suitable substrate for any mutant protein that has been altered to form an ultra-stable or covalent bond with its substrate that would ordinarily only transiently bound by the protein. In some embodiments, the protein is a mutant hydrolase or dehalogenase. In some embodiments, the protein is a mutant dehalogenase and the substrate is a haloalkane. In some embodiments, the haloalkane comprises an alkane (e.g., C₂-C₂₀) capped by a terminal halogen (e.g., Cl, Br, F, I, etc.). In some embodiments, the haloalkane is of the formula A-X, wherein X is a halogen (e.g., Cl, Br, F, I, etc.), and wherein A is an alkane comprising 2-20 carbons. In certain embodiments, A comprises a straight-chain segment of 2-12 carbons. In certain embodiments, A is a straight-chain segment of 2-12 carbons. In some embodiments, the haloalkane may comprise any additional pendants or substitutions that do not interfere with interaction with the mutant dehalogenase.

In some embodiments, a capture agent is a SNAP-Tag and a capture element is benzyl guanine (See, e.g., Crivat G, Taraska JW (January 2012). Trends in Biotechnology 30 (1): 8-16.; herein incorporated by reference in its entirety). In some embodiments, a capture agent is a CLIP-Tag and a capture element is benzyl cytosine (See, e.g., Gautier, et al. Chem Biol. 2008 Feb; 15(2):128-36.; herein incorporated by reference in its entirety).

Systems comprising mutant proteins (e.g., mutant hydrolases (e.g., mutant dehalogenases) that covalently bind their substrates (e.g., haloalkane substrates) are described, for example, in U.S. Pat. Nos. 7,238,842; 7,425,436; 7,429,472; 7,867,726; each of which is herein incorporated by reference in their entireties.

In some embodiments, a functional element is an affinity element (e.g., that binds to an affinity agent). Examples of such pairs would include: an antibody as the affinity agent and an antigen as the affinity element; a His-tag as the affinity element and a nickel column as the affinity agent; a protein and small molecule with high affinity as the affinity agent and affinity element, respectively (e.g., streptavidin and biotin), etc. Examples of affinity molecules include molecules such as immunogenic molecules (e.g., epitopes of proteins, peptides, carbohydrates, or lipids (e.g., any molecule which is useful to prepare antibodies specific for that molecule)); biotin, avidin, streptavidin, and derivatives thereof; metal binding molecules; and fragments and combinations of these molecules. Exemplary affinity molecules include His5 (HHHHH)(SEQ ID NO: 1), HisX6 (HHHHHH)(SEQ ID NO: 2), C-myc (EQKLISEEDL) (SEQ ID NO: 3), Flag (DYKDDDDK) (SEQ ID NO: 4), SteptTag (WSHPQFEK)(SEQ ID NO: 5), HA Tag (YPYDVPDYA) (SEQ ID NO: 6), thioredoxin, cellulose binding domain, chitin binding domain, S-peptide, T7 peptide, calmodulin binding peptide, C-end RNA tag, metal binding domains, metal binding reactive groups, amino acid reactive groups, inteins, biotin, streptavidin, and maltose binding protein. Another example of an affinity molecule is dansyllysine. Antibodies that interact with the dansyl ring are commercially available (Sigma Chemical; St. Louis, Mo.) or can be prepared using known protocols such as described in Antibodies: A Laboratory Manual (Harlow and Lane, 1988).

EXAMPLE 11

Experiments were conducted during development of embodiments herein to derive a comprehensive analysis of intracellular kinase target engagement using NanoBRET™ tracers derived from CC-1294 versus NanoBRET™ tracers derived from novel inhibitors. In wells of 96-well plates, 20,000 HEK293 cells/well were transfected with pFN31K and pFN32K plasmids for expression of kinase/NanoLuc® (Nluc) fusion proteins. Transfections were performed using 3:1 FuGENE HD:plasmid ratios. 24 hours post transfection, cells were treated for 2 hours in the presence of 0.5 uM CC-1804, CC-1852, or 1 uM CC-1294. After incubation, NanoBRET™-Target Engagement (TE) substrate/inhibitor solution was added to a final concentration of 1X. NanoBRET was measured on a Glomax® Discover plate reader. To determine relative BRET signals, BRET arising from the tracer was divided by BRET in the absence of tracer. As demonstrated in FIG. 1A-B, unexpectedly broad spectrum target engagement/kinase profiling was observed with CC-1804 and CC-1852 compared to CC-1294.

EXAMPLE 12

Experiments were conducted during development of embodiments herein to demonstrate novel live cell target engagement assays uniquely enabled by CC-1804, which are not enabled by CC-1294. In wells of 96-well plates, 20,000 HEK293 cells/well were transfected with pFN31K and pFN32K plasmids for expression of kinase/NanoLuc® (Nluc) fusion proteins. Transfections were performed using 3:1 FuGENE HD:plasmid ratios. 24 hours post transfection, cells were treated for 2 hours in the presence of varying concentrations of tracer and varying concentrations of control inhibitor as indicated in FIG. 2A-C. After incubation, NanoBRETTM-TE substrate/inhibitor solution was added to a final concentration of 1×, and BRET was measured on a Glomax® Discover plate reader.

EXAMPLE 13

Experiments were conducted during development of embodiments herein to analyze the broad-spectrum intracellular kinase target engagement of parental molecules CC-1861 versus CTx-0294885 (FIG. 3 ). In wells of 96-well plates, 20,000 HEK293 cells per well were transfected with kinase/Nluc fusions expressed from pFN31K and pFN32K plasmids. Transfections were performed using 3:1 FuGENE HD:plasmid ratios. 24 hours post transfection, cells were treated for 2 hours in the presence of NanoBRET™ tracers (K4, K5, K7, K8, K9, K10, K11) introduced at optimized concentrations in the presence of test compounds 300 nM CC-1861, 300 nM CTx-0294885, or 0.1% DMSO (vehicle). Analysis was also performed in using untagged Nluc to determine zero BRET (full occupancy control sample). After incubation, NanoBRET™-TE substrate/inhibitor solution was added to a final concentration of 1×. NanoBRET was measured on a Glomax® Discover plate reader.

To generate raw BRET ratio values, the acceptor emission value (e.g. 610 nm) was divided by the donor emission value (e.g. 450 nm) for each sample.

Determine Fractional Occupancy with the following equation;

% Occupancy=[1−(X−Z)/(Y−Z)]*100

where X=BRET in the presence of the test compound and tracer, Y=BRET in the presence of tracer only (zero occupancy control), and Z=BRET for the full occupancy control (ie., BRET from the untagged Nluc fusion).

Of the 200 kinases evaluated 71 kinases preferred CC-1861 to CTx; only 4 kinase preferred CTx over CC-1861 (FIG. 5 ).

EXAMPLE 14

Experiments were conducted during development of embodiments herein to demonstrate the increased kinase affinity of unmodified CC-1861 versus CTx-0294885. In wells of 96-well plates, 20,000 HEK293 cells per well were transfected with kinase/Nluc fusions expressed from pFN31K and pFN32K plasmids. Transfections were performed using 3:1 FuGENE HD:plasmid ratios. 24 hours post transfection, cells were treated for 2 hours in the presence of tracer and varying concentration of control inhibitor indicated. After incubation, NanoBRET™-TE substrate/inhibitor solution was added to a final concentration of 1×, and BRET was measured on a Glomax® Discover plate reader.

CC-1861 shows increased inhibitor potency compared to CTx (FIG. 7 ). CC-1861 had greater than 0.5 log shift in potency improvement compared to the CTx-0294885 for many of the kinases screened thus demonstrating CC-1861 as an improved broad-spectrum kinase binding agent (FIG. 8 ).
